CULTIVATO R.

SPECIFICATION forming part of Letters Patent No. 311,645, dated February 3, 1885.

Application lcd April 30, 1884. (No model.) l

To all whom it may concern:

Be it known that I, RICHARD ORAcRxEr. a citizen of the United States, residing at Berwick, in the county of Warren and State of Illinois, have invented certain new and useful Improvenientsin Gultivators, of which the following is a specilication, reference being had therein to the accompanying drawings.

This invention relates to improvements in 1o arched wheel-plows, and is intended to straddle a row of plants in cultivating the same, and has for its object to provide an adjustable flexible coupling and a drag to carry the cultivator-plows when out of the ground, which t5 may be attached to any cultivator. This object is attained by the devices illustrated in the accompanying drawings, forming a part of this specitication, in which- Figure l. is a view showing an arched axle.

2e Fig. 2 is a side elevation which shows the arched axle, the coupling, plowbeam, drag, and plows, one of the wheels' being removed. Fig. 3 is a transverse section of theaxle on the line :r of Fig. el. Fig. 4 is a plan.

The letter A indicates an arched axle having slots a for the passage of bolts C, which are secured to the forked pieces B. The bolts C are provided with nuts C', which, when loosened, permit the bolts C to be moved in a 3o longitudinal direction from one end to the other of either of the slots a, for the purpose of adjustment of the couplings, together with the plow-beams G and plows H, so as to regulate the distance of the plows with regard to the plants under cultivation. The forked pieces or yokes B are perforated to receive the bolts C, and also to receive bolts e, which pass through longitudinal holes in the pieces I), and form pivots, upon which they turn 4o freely. Attached to piece D, and placed at right angles thereto, is the piece D. These two parts may be made of separate pieces or of a single casting or forging. The part D has a longitudinal hole, y, to receive a bolt or rivet,

g', which passes through the hole g, and also through suitable openings in the clevis E, upon which the latter turns as upon a pivot. A bolt, L, passes through an opening in the clevis and through a slot, F', formed by joining two 5o pieces of metal, F, together by means of rivets f. The pieces F, when joined, form a wedge-shape casting, which is secured to the end ofthe plow-beam G by having a suitable opening therein to receive it, and by bolts N. which pass transversely through the beam and 5 5 casting.

H H are plows of any of the usual forms in general use, suitably attached to the beam G.

K is a drag pivotcd to the beam G. It is perforated at the top to receive one end of a 6o metal rod, M, which is bent to the proper angle for this purpose. The other end of this bar is twisted, so as to form a stop when inserted inthe forked openings or hooks of two pieces of metal, I l, secured to the upper side ofthe plow-beam G, so as to maintain the drag in a position to permit the plows to enter the ground, or, when the cultivat-oris to be moved to another place, to lift the plows and hold them clear ofthe ground. 7o

It will be readily seen that the slotsa in the arched axle A will permit the couplings to the beams G to beadj usted as to the distance which it may be desired to place them apart, and that by making the couplings inthe manner hereinbet'ore described t-he connection between the plow-beams G and the axle of the machine will be iiexible, or in the nature of a universal joint, whereby the axle and the plows will be able to assume various positions 8o in relation to each other.

Having described my invention, what I desire to secure by Letters Patent and claim isl. In a cultivator, the combination of arched axle A, slots a, bolts C, yokes B, parts D D', 85 provided with bolts e, clevis E, bolt g', bolt L, and casting F, with a plow-beam, G,sub stantially as described, and for the purposes set forth.

2. In a cultivator, the plow-beam G, in comgr bination with drag K, metal bar M, hooks I I', and plows H H, substantially as described, and for the purposes set forth.

In testimony whereof Iafiix my signature in presence of two witnesses.

RICHARD CRACRAFT.
